For about $20 you can buy several sets of cheaters ....I settled on a set of +1.25 for best overall usage in action shooting.... sights good, targets OK.

For target shooting there are several makers of prescription glasses that have a small insert in the upper left corner of the right lens (right hand shooter) the rest of the lens can be clear or prescription.

" Hansen's Eagle Eye" is one expensive...... SSP Eyewear is another less expensive brand.... both are safety glasses.
